  For this reason, due to restrictions on the vehicle body design, for example, when the lower end of the back door protrudes to the rear of the vehicle body relative to the hinge shaft, the back door opening end is positioned away from the hinge shaft toward the rear of the vehicle body. In this case, when the back door is opened and closed, the vicinity of the lower end protruding rearward may interfere with the vicinity of the back door opening of the vehicle body.

  In order to avoid this interference, it is conceivable to offset the lower end portion of the back door protruding rearward inward in the vehicle width direction with respect to the hinge shaft. However, in this case, it is necessary to cover the offset region by forming a projecting portion integrally with a member on the vehicle body side such as a body side outer panel or a rear bumper.

  As described above, when the protruding portion is integrally formed on the vehicle body side member on the hinge shaft side, the left opening specification in which the hinge shaft is set on the left side in the vehicle width direction and the right side in which the hinge shaft is set on the right side in the vehicle width direction. With the opening specification, it is necessary to separately prepare the members on the vehicle body main body in which the projecting parts are integrally formed, which hinders the common use of the members (parts) and increases the cost.

  Therefore, the present invention avoids interference between the back door on the hinge shaft side and the periphery of the back door opening of the vehicle body even when the hinge shaft and the back door opening end are located apart from each other as viewed from the hinge axis. The purpose of this is to make it possible to share the vehicle body side member between the left-opening specification and the right-opening specification of the back door.

  According to the present invention, the outer edge in the vehicle width direction of the lower end portion of the back door in the fully closed state is positioned on the inner side in the vehicle width direction than the hinge member, and the vehicle width direction of the vehicle width direction outer edge and the vehicle body side member A cover member is attached to the vehicle body side between the inner edge portion.

  According to the present invention, the outer edge in the vehicle width direction of the lower end portion of the back door in the fully closed state is located on the inner side in the vehicle width direction with respect to the hinge member, Since the cover member is attached to the vehicle body side between the vehicle body direction side member and the vehicle width direction inner edge, the vehicle body side member does not need to have a shape protruding inward in the vehicle width direction on the hinge member side. Therefore, even if the hinge member and the back door opening end are separated from each other, while avoiding interference between the back door and the periphery of the back door opening of the vehicle body, the back door left opening specification and the right opening specification, The vehicle body side member can be shared.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The back door 3 is a lateral opening that can be opened and closed in the left-right direction around a hinge member 9 provided on the left side of the vehicle as viewed from the rear of the vehicle. The hinge member 9 is set at a vertical position substantially corresponding to the window opening 1a of the rear side window.

  Further, as shown in the side view of FIG. 2, the back door 3 in the fully closed state is generally seen although the lower part is slightly inclined so as to be positioned behind the upper part (right side in FIG. 2) from the upper part. The shape extends substantially in the vertical direction. The lower end portion 3 a of the back door 3 protrudes rearward from the vicinity of the abutting portion 13 between the body side outer 11 of the vehicle body 1 and the rear bumper 5, and is inclined more greatly, and is positioned rearward of the hinge member 9. .

  At the lower end of the back door 3 at the end in the vehicle width direction on the hinge member 9 side, a vertically elongated cutout 3b is formed. A cover member 15 whose outer shape is a substantially rectangular shape is attached to the vehicle body 1 at a position corresponding to the notch 3b when the back door 3 is fully closed. That is, the cover member 15 includes a vehicle width direction outer edge 3a1 corresponding to the notch 3b of the lower end 3a when the back door 3 is fully closed, and a vehicle body side member (body side outer 11 and rear bumper 5). Are attached to the vehicle body 1 side between the inner edges 11a and 5a1 in the vehicle width direction.

  3 is a cross-sectional view taken along the line AA of FIG. 2, and the hinge shaft 9a of the hinge member 9 serving as the rotation center of the back door 3 is located on the vehicle interior side in the vehicle width direction with respect to the body side outer 11 described above. In FIG. 3, the rotation locus of the back door 3 around the hinge shaft 9a is indicated by a two-dot chain line.

  Here, the back door 3 in the fully closed state indicated by the solid line in FIG. 3 has a vehicle width direction outer edge 3a1 corresponding to the above-described notch 3b of the lower end 3a at a position closer to the vehicle than the hinge shaft 9a of the hinge member 9. It is located inside in the width direction. The hinge member 9 shown in FIG. 3 is illustrated as a virtual position in plan view.

  Further, as described above, the lower end portion 3a of the back door 3 is located behind the hinge member 9, so that the back door corresponding to the hinge shaft 9a of the hinge member 9 and the lower end portion 3a of the back door 3 is used. The opening ends 1b are not at positions where they overlap each other in plan view, but are at positions away from each other.

  Next, the cover member 15 will be described with reference to FIG. The cover member 15 includes an outer cover 17 and an inner cover 19. The cover member 15 inserts and locks the locking claw 17a of the outer cover 17 into the locking hole 19a of the inner cover 19 from the state of FIG. 4B, and the screw 21 shown in FIG. 4 is inserted into the screw insertion hole 19b from the back side and screwed into the screw hole 17b of the outer cover 17, and the assembled state as shown in FIG.

  Then, the cover member 15 integrated as shown in FIG. 4A is fitted and fixed to the body 1 side of the clip 23 provided on the back side of the inner cover 19, and the screw 25 shown in FIG. It is inserted into the screw insertion hole 19c of the inner cover 19 and fixed to the vehicle body 1 by screwing and fixing to the vehicle body 1 as shown in FIG. At this time, the attachment portion by the clip 23 and the screw 25 is positioned on the back side of the fully closed back door 3.

  In the cover member 15 attached in this manner, the outer surface 17c of the outer cover 17 forms the same continuous outer surface with respect to the outer surfaces of the body side outer 11, the rear bumper 5, and the fully closed back door 3. The outer cover 17 has a substantially rectangular shape as viewed from the outside of the vehicle body. The outer cover 17 having a substantially rectangular outer shape has an inner long side portion 17d on the inner side in the vehicle width direction and an outer long side portion 17e on the outer side in the vehicle width direction. Inclined to be located.

  As described above, in the vehicle body rear portion structure including the laterally open back door in the present embodiment, the notch 3b is formed at the vehicle width direction end of the lower end 3a of the back door 3 on the hinge member 9 side. The outer edge 3 a 1 in the vehicle width direction of the lower end 3 a of the vehicle 3 is positioned further inward in the vehicle width direction than the hinge member 9. Therefore, as shown in FIG. 3, even if the back door 3 is opened from the fully closed state indicated by the solid line as shown by the two-dot chain line, or conversely the closing operation is performed from the open state, The edge 3a1 does not interfere with the cover member 15 (corresponding to the back door opening end 1b) on the vehicle body 1 attached at a position corresponding to the notch 3b.

  Further, regarding the back door for right opening in the vehicle body 1 of the present embodiment, that is, the back door set at the right end in the vehicle width direction when the hinge member is viewed from the rear of the vehicle body, the above described left opening back door A notch portion similar to the notch portion 3b is formed at the lower end portion on the right side in the vehicle width direction so that the left and right sides are reversed with respect to the shape. And the cover member of the shape where right and left reversed with respect to the above-mentioned cover member 15 is attached to the position corresponding to this notch. Of course, the left cover member 15 is unnecessary at this time.

  Accordingly, the back door for the right opening is also the same as the back door 3 for the left opening described above, and the vehicle body main body 1 side where the outer edge in the vehicle width direction of the lower end is attached at a position corresponding to the notch. It does not interfere with the cover member (corresponding to the back door opening end).

  At this time, in this embodiment, the cover member 15 is attached as a separate member from the body side outer 11 and the rear bumper 5 at a position corresponding to the notch 3b. For this reason, even when the back door is attached to the vehicle body 1 for the left opening as in the above-described back door 3, or when the back door is attached to the vehicle body 1 for the right opening, the vehicle body 1 (which is the vehicle body side component) The body side outer 11) and the rear bumper 5 can be shared without changing the shape.

  On the other hand, when the body side outer 11 and the rear bumper 5 are partly projected at positions corresponding to the notches 3b of the left opening back door 3, the back door is used for right opening. When assembling the body side outer 11 and the rear bumper 5 to the vehicle body 1, the lower end corner of the back door interferes when the projecting portion is fully closed. It becomes necessary to prepare a vehicle body side part having a protruding portion on the opposite side.

  Thus, in this embodiment, the vehicle width direction outer side edge 3a1 of the lower end 3a of the back door 3 in the fully closed state is located on the vehicle width direction inner side than the hinge member 9, and corresponds to this positional relationship. Thus, the cover member 15 is attached to the vehicle body 1.

Therefore, as shown in FIG. Even if the door opening end 1b is positioned away from the hinge axis, the back door 3 can be opened to the right and the left side while avoiding interference between the back door 3 and the periphery of the back door opening of the vehicle body 1. The vehicle body side member can be shared with the opening specification.

  Further, the rear bumper 5 of the present embodiment is attached to the vehicle body 1 with the back door 3 opened. For this reason, the rear bumper 5 is attached to the rear bumper 5 by attaching a separate part as the cover member 15 without integrally providing a protruding portion that partially protrudes at a position corresponding to the notch 3b of the back door 3. It can be attached without interfering with the vehicle body 1 and the back door 3.

  Further, in the present embodiment, the inner side in the vehicle width direction of the protruding portion 5a of the rear bumper 5 is disposed on the outer side in the vehicle width direction opposite to the outer edge portion 3a1 of the lower end portion 3a of the back door 3 with the cover member 15 therebetween. The edge 5a1 is located. For this reason, the rear bumper 5 does not need to have a protruding shape corresponding to the cutout portion 3b of the back door 3. Therefore, as shown in FIG. 3, the hinge shaft 9a and the back door opening end 1b are separated from each other. However, the rear bumper 5 can be shared by the right-opening specification and the left-opening specification while avoiding interference between the back door 3 and the periphery of the back door opening of the vehicle body 1.

  In the present embodiment, the vehicle side inner edge of the body side outer 11 is disposed on the outer side in the vehicle width direction opposite to the outer edge 3a1 of the lower end 3a of the back door 3 with the cover member 15 therebetween. 11a is located. For this reason, it is not necessary for the body side outer 11 to have a protruding shape corresponding to the notch 3b of the back door 3, and therefore the hinge shaft 9a and the back door opening end 1b are separated from each other as shown in FIG. Even if it exists, the body side outer 11 can be shared by the back door 3 by the right opening specification and the left opening specification, avoiding interference with the back door opening part periphery of the vehicle body main body 1. FIG.

  Further, in the present embodiment, the cover member 15 has the attachment portion by the clip 23 and the screw 25 to the vehicle body 1 located on the back side of the back door 3 in the fully closed state.
